A train covers a distance of 10 km in 12 minutes. Find its speed (in km/h).

Correct option is C

Given:
Distance = 10 km
Time = 12 minutes

Formula Used:

​$$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$$

Solution:

Convert time to hours:

12 minutes = $$\frac{12}{60}$$ = 0.2 hours

Speed = $$\frac{10}{0.2} = \frac{100}{2}$$​ = 50 km/h

So, the speed of the train is 50 km/h.

Thus, the correct answer is (c).
